SOLE FITTING Filed April 24, 1954 Ti 2 d WVE/VTUR/ Patented July 7, 1936 UNITED STATES SOLE FITTING William R. Bolton, Chicago, Ill., assignor to United Shoe Machinery Corporation, Paterson, N. J., a corporation of New Jersey Application April 24, 1934, Serial No. 722,161

4 Claims. (01.12-146) This invention relates to sole fitting and is herein illustrated and described with reference to a method of operating upon double-lipped insoles, and also to a sole which has been thus operated upon.

in United States Letters Patent No. 1,213,770,

granted January 23, 1917, upon an application of Albert E. Johnson.

In order to improve the manufacture of such insoles, the present invention comprises a method which consists in providing a double lipped insole and removing material from the lips thereof at a locality near one of the ends of the lips to form notches which facilitate the entering beneath said lips of lip-raising instrumentalities; and preferably, simultaneously with the making of the notches, making cuts connecting said notches to ensure that, irrespective of the widths of the lips, the ends bf the lips shall be severed from their outer edges to their points of attachment to the insole. In carrying out the method, a novel product is produced, namely a double lipped insole having the above described notches and preferably'also the cuts which connect the notches.

The improved machine disclosed but not claimed herein constitutes the subject matter of my divisional application Serial No. 30,490, filed July 9, 1935.

Referring now to the accompanying drawing:

Fig. 1 is a view in perspective illustrating the step of forming cuts in the lips of an insole by a machine;

tends continuously around the shank and forepart of the insole. In accordance with the improved method, material is removedfrom one end of the outer lip L to form a U-shaped notch N, and material is similarly removed fromthe inner lip L to form a U-shaped notch N. Connecting the notches N and N and extending through the between substance is a straight out C. The notches N and N and the cut .0 may conveniently be made by a knife suchas that shown inFig. 2 in a machine of the type shown in Fig. 1, which will presently be described in detail. At the other end'of the lips L and L, there may be conveniently formed a straight cut C to mark definitely the termination of the lips. The cuts C and C are usually made at about the heel-breast line of the sole. After these operations havebeen performed upon the sole S, the lips L and L are raised and secured together by cement or stitching to form cir a ridge. The raising of the lips may convenient- 1y be accomplished by the use of a machine such as that disclosed in the above-mentioned Letters Patent No. 1,213,770, which (as shown in Fig. 3 of that patent) is provided with a pair of plowlike members for engaging the under surface of the lips to turn the lips up. The notches N and N facilitate the entrance of these plow-like members beneath the lips. As shown in Fig. 3, one of the plows I0 is in the process of entering beneath the lip L and the other plow 8 is in the process of entering beneath the lip L. As the sole is fed, the plows advance progressively beneath the lips and emerge at the cut C.

It will be noted that, according to the method as so far described, the cuts N, N and C are formed in an insole which has already been channeled. It may sometimes be convenient however, and the result will be the same, to, make these cuts in an insole blank before the lips L and L are formed by the channeling operation.

In Fig. 1 are shown the operating instrumentalities of a machine for forming the abovementioned notches and cuts. This machine consists of a frame I2 having a raised portion I4 which serves as a work support. The heel portion of the: sole S is centered upon the work table M by a pair of gages l6 which are controlled by mechanism similar tothat. disclosed in United States Letters Patent No. 1,113,544, granted October 13, 1914, upon an application of Miller Cook, Jr. As disclosed in that patent, the centering gages are mounted for transverse movement with respect to the center line of the machine, being connected by gearing in such manner as to insure that both gages are always at an equal distance from the center line and 'being urged toward the center line by aspring For a. more complete understanding 10f the *mechahism for centering the gages I6, reference may be had to the above-mentioned Letters Patent No. 1,'113,544. Adjustably mounted on the Work table I4 is a gage I8 for engaging the rearend of the sole. A bridge member!!! serves to hold the sole'down against any tendency of the gages Hi to raise it. The machine is provided with a knife 22 having a cutting edge 24 'whichqis shaped to form the notches N and N andthe straight out C. The machine is also provided;

with a knife 26 having a'straight edge to formthe rcut C The knives 22' and 26 may convemently be mounted and operated in the same manner as the knives disclosed in the above- V mentioned Letters Patent No. 1,113,544.

In the operation of the machine, the heel end of thesole S is passed beneath the bridge 20 and between the gages l6 until therear end of the sole abuts the gage [8. 'Upon starting the machine, the knives 22 andv 23 descend and 7 make their respective cuts, the positionv (for-V wardly or rearwardly) of which cuts is determined by the adjustment of the gage: I8. .The

.c knives may be lowered and raised continuously,

or, if desired, the machine may be provided with a'mechanism for stopping it automatically after each'cycle of movement of the knives. V
